Detailed Description

template<typename Lockable>
struct sigslot::observer_base< Lockable >

Observer is a base class for intrusive lifetime tracking of objects.

This is an alternative to trackable pointers, such as std::shared_ptr, and manual connection management by keeping connection objects in scope. Deriving from this class allows automatic disconnection of all the slots connected to any signal when an instance is destroyed.

Member Function Documentation

template<typename Lockable >

void sigslot::observer_base< Lockable >::disconnect_all ( )

inlineprotected

Disconnect all signals connected to this object.

To avoid invocation of slots on a semi-destructed instance, which may happen in multi-threaded contexts, derived classes should call this method in their destructor. This will ensure proper disconnection prior to the destruction.
